This research direction explores emergent physical phenomena in two-dimensional materials arising from the control of layer number, stacking configuration, twist angle, interfaces, and symmetry.

Two-dimensional materials provide highly tunable interlayer degrees of freedom. By precisely engineering stacking configurations and rotational alignment, electronic band structures can be reconstructed, giving rise to moiré superlattices, ferroelectricity, correlated electronic states, topological phenomena, and other emergent quantum properties.

We construct high-quality moiré heterostructures through van der Waals assembly while also exploring direct growth of two-dimensional quantum materials with controlled stacking and twist using CVD and related synthesis techniques. Their electronic structures and quantum properties are investigated using low-temperature transport, optical spectroscopy, and scanning-probe measurements.
